You drop two balls of equal diameter from the same height at the same time. Ball 1 is made of metal and has a greater mass than
Lelechka [254]

Answer:

The drop time ball 1 is less than the drop time of ball 2. A further explanation is provided below.

Explanation:

The net force acting on the ball will be:

⇒ F_{net}=mg-F_r

Here,

F = Force

m = mass

g = acceleration

Now,

According to the Newton's 2nd law of motion, we get

⇒ F_{net} = ma

To find the value of "a", we have to substitute "F_{net}=ma" in the above equation,

⇒ ma=mg-F_r

⇒    a=g-\frac{F_r}{m}

We can see that, the acceleration is greater for the greater mass of less for the lesser mass. Thus the above is the appropriate solution.
